Polk Audio specifies therecommended amplification range
f
or each of its passive (non-amplified) loudspeakers. Typically
that specificationwill be expressed as arangeof power such
a
s 20-200 W(per channel). It is important to understand
w
hat those numbers mean whenchoosing areceiveror
a
mplifier for your Polk loudspeakers. The lower number
indicates the lowest continuous rated power that will yield
a
cceptable performancein a typicallisteningenvironment.
The higher number indicatesthe highest per channel power
t
hat should be used with your Polkspeakers. That number
should not be confused witha “Power Handling” specification
and it does not imply that thespeaker willsafelyhandle
t
hat full amount of poweron a long-term basis.We specify
a wide range of power ratings because not all electronics
manufacturers use thesame method forratingpower.
In fact, high qualitylower-rated amplifiers sound better and
play louder than low quality units with a higher power rating.
Automobile horsepoweris a goodanalogy. Your car probably
has far more horsepower than it needs for your daily commute
and is likely capableof going well over120mph(190km/hr).
Having that extra power is good for on-ramp acceleration
and danger avoidance (like getting away from brain-eating
zombies) but that doesn’t meanthat it is advisable to operate
your car on North American highways at full power and
maximum speed for an extended period of time. Just ask
your local state trooperif youare in doubt. Similarly, we
recommend using amplifiers andreceivers with rated power
above the Power Handlinglimitsof ourspeakers because
having extra poweravailablefor shortterm peaks is conducive
to better sound quality,maximum dynamicrange and effortless
high volume output. But we strongly urge you not to use the
full power of your amplifier or receiver for daily listening.
Loudspeakers can be damagedwhen an amplifier, regardless
of its wattage, is made to play at higher listening levels than
its power can clearlyproduce. Operation at this level can result
in very high levels of audibledistortion originating in the
amplifier, which can adda harsh, grittysound to your listening
material. If you hear distortion—turn the volume down
or risk damaging your speakers. You can damage just about
any speaker, regardless of power rating, if you drive an
